[v1.0.1] Salesforce Member__c & session_id support

Changes

Salesforce

• Switched all Salesforce object references from User__c to Member__c (correct custom object per datamapping document)
• Updated health check queries to use Member__c instead of Contact/Account
• Updated GitHub Secrets with the project's real Salesforce org credentials

session_id

• session_id is now read from incoming new_registration body and forwarded in the Kassa XML payload

docker-compose

• Added docker-compose.yml for local development (local RabbitMQ only — production uses the team's RabbitMQ)

Heartbeat

• Removed crm-heartbeat from docker-compose.yml — heartbeat is Team Monitoring's responsibility
